For A7670E

[famtory]

Hello I have "https://github.com/Xinyuan-LilyGO/T-A7670X" This source doesn't work on "A7670". I checked that the rx and tx pin numbers are different. But still not working.

Ey... have you checked the libraries specific from lilygo? check their fork. Anyway, maybe this response is too late. Have you build your traccar with A7670?
